Adaptation to salt stress in rice - How jasmonates contribute to the response to high salinity

The response of two jasmonic acid (JA) biosynthesis rice mutants (cpm2 and hebiba) to salt stress was investigated in comparison to their wild type. The JA-biosynthesis mutants showed a less-salt sensitive phenotype compared to the wild type. Interestingly, the transfer of sodium ions from roots to shoots was reduced in JA biosynthesis mutants as both cpm2 and hebiba plants accumulated smaller amounts of Na+ ions in their leaves, while roots of both contained similar quantities
